MasTec, Inc. completed a new debt financing, issuing $650.0 million aggregate principal amount of 5.850% senior unsecured notes due 2036. These 2036 Senior Notes were issued under MasTec’s existing 2009 base indenture, as supplemented by a twenty-second supplemental indenture with U.S. Bank Trust Company, National Association as trustee.
The notes are senior unsecured obligations of MasTec and rank equally with its other senior unsecured debt, but are effectively subordinated to any secured indebtedness and structurally subordinated to obligations of its subsidiaries, which do not guarantee the notes. The notes bear interest at 5.850% per year, payable on March 30 and September 30 beginning March 30, 2027, and mature on September 30, 2036. MasTec may redeem the notes, in whole or in part, at redemption prices specified in the indenture, which also includes customary events of default and remedies.
